    Abstract: The present invention provides a method of manufacturing a PDP that prevents defects due to dust adhering to a photomask, for example, from occurring in a structure of the PDP. In photolithography, exposure is performed twice in a same process, and photomask (22) is moved within an allowable range of displacement in an exposure pattern, between a first and a second exposures. Photomask (22) is exposed twice in total before and after moving photomask (22). Region (21a), an unexposed region due to interruption of dust (22b) attached to photomask (22), can be suppressed, enabling pattern exposure on photosensitive Ag paste film (21) to be favorably performed.

    Abstract: A double exposure process is performed using a halftone phase shift mask (11) including gate patterns (1), assist patterns (2a) and (2b) with different resoluble line widths, and an assist pattern (2c) with a line width equal to or smaller than a resolution limit which are respectively inserted into portions in each of which a distance between the gate patterns (1) is large, and a Levenson phase shift mask (11) including shifter patterns (3) corresponding to the gate patterns (1) of the photomask 11. On this occasion, the assist patterns (2a), (2b), and (2c) are erased and only the gate patterns (1) are transferred. Consequently, when patterns are transferred by the double exposure process, a common depth of focus of the patterns is improved and highly uniform line widths are realized, which makes it possible to manufacture a highly reliable semiconductor device.

    Abstract: A method of forming a feature pattern in a photosensitive layer includes forming the photosensitive layer on a substrate, providing a first mask having a first opaque area thereon, and performing a first exposure process with a first dose to form a first unexposed image in the photosensitive layer. The method further includes performing a second exposure process with a second dose to expose sidewalls of the first unexposed image so that the sidewalls of the first unexposed image receive at least a portion of the second dose thus forming a second unexposed image in the photosensitive layer, and developing the photosensitive layer with a developing process to form the feature pattern and to create features having smaller widths than those which would result in developing the photosensitive layer of the first unexposed image.

    Abstract: An initial layout of an integrated circuit device is separated into a set of definitions for use in a multiple exposure fabrication process. The separation begins with reading a portion of the initial layout and identifying one or more target features within the initial layout. Further, a first revised layout definition is created for a first mask and a second revised layout definition is created for a second mask. The first revised layout definition includes the target features inside the dark-field content. In addition, in one embodiment, the first revised layout definition includes clear areas around each target feature. The second layout definition includes one or more dark features inside the bright-field content. These dark features, when used in the multiple exposure fabrication process, will overlap the target features. The first and second masks may be binary masks, attenuated phase-shifting masks (PSMs) or a combination of a binary mask and an attenuated PSM.

    Abstract: A method for forming a clear code mark that is independent of backend planarization by adding an extra exposing step to the normal photolithography process is described. A layer to be patterned is provided on a substrate. A photoresist layer is coated overlying the layer to be patterned. The photoresist layer is first exposed through a code mask and second exposed through a patterning mask. The photoresist layer is developed to form a photoresist mask having a code mark pattern from the code mask and a device pattern from the patterning mask. The layer to be patterned is etched away where it is not covered by the photoresist mask to form simultaneously device structures and a code mark in the fabrication of an integrated circuit device.
